Aca-Awesome! The ‘Vanderpump Rules’ Kids Sang a Christmas Carol With the ‘Pitch Perfect 3’ Cast

File this under “things we never thought would happen in a million years.” A handful of cast members from Bravo’s Vanderpump Rules teamed up with the ladies of Pitch Perfect 3 to film a Christmas-themed music video to celebrate the upcoming premiere of the film franchise’s third and final installment. While the collab, which dropped on Monday, Dec. 11, is completely unexpected, we must admit that it turned out to be pretty aca-awesome.

Chrissie Fit, who plays Flo in the movie, opens the group’s take on the holiday classic “12 Days of Christmas,” and gives thanks for her “kick-a– Bella family.” Next up is former SURver Kristen Doute, who pokes fun at her past relationships with Tom Sandoval and James Kennedy, who also appear in the clip. “On the second day of Pitchmas, my true love gave to me two former flames,” Kristen — who, um, we had no idea had a voice — sings, before Tom chimes in, “And a bad hangover from that part-ayyy.”

Kristen then continues to show off her surprisingly strong vocal chops, singing “Cups (When I’m Gone),” made famous by Anna Kendrick in 2012. Then, there’s some enthusiastic (albeit painful-to-watch) dancing from both the Barden Bellas and the Pump Rules kids. Before the holiday ditty wraps up, Scheana Marie low-key references her split from ex-husband Mike Shay when she tells the camera that her “true love” brought her “five non-engagement rings.” (So savage.)

One day after the promo aired, several VPR stars walked the red carpet at the Pitch Perfect 3 premiere in LA. Kristen, who posed for photos with her “Witches of WeHo” comrade Katie Maloney, took to Twitter to let her fans know just how much she loved getting to work with Chrissie on their “Pitchmas” project. “I don’t think I’ve ever met a kinder (or tinier) person than @chrissiefit,” she wrote. “BTW.. She’s such an adorably-talented-boss-a—b—h. ???”

Vanderpump Rules airs on Bravo Mondays at 9 p.m. EST. Pitch Perfect 3 hits theaters Dec. 22.
